>Description:
	According to the Single UNIX Specification, Version 2 (ref
	http://www.opengroup.org/onlinepubs/007908799/xns/gethostbyaddr.html)
	the len (second parameter) of gethostbyaddr should be a size_t
	and is currently an int on NetBSD.

>How-To-Repeat:
	By inspection.

>Fix:
	Change the len parameter to a size_t instead of an int?

	Two ABI issues come to mind - changing from a signed type to
	an unsigned type (size_t is unsigned on all platforms), and
	changing from an int size type to a long sized type.  The only
	ports where size_t is long are alpha, sparc, sparc64 and ELF-vax
	(whether or not this is a bug is a separate question).
